APW7074

Synchronous Buck PWM Controller

General Description

Features

TheAPW7074 uses fixed 300KHz switching frequency,

voltage mode, synchronous PWM controller which

drivesdualN-channelMOSFETs. Thedeviceintegrates

all of the control, monitoring and protecting functions

into a single package, provides one controlled power

output with under-voltage and over-current protections.

Single 12V Power Supply Required

0.8V Reference with 1% Accuracy

Shutdown and Soft-start Function

300KHz Fixed Switching Frequency

Voltage Mode PWM Control Design

Up to 100% Duty Cycle

The APW7074 provides excellent regulation for

output load variation. The internal 0.8V temperature-

compensated reference voltage is designed to meet

the requirement of low output voltage applications.

Under-Voltage Protection

Over-Current Protection

SOP-14 Package

The APW7074 with excellent protection functions:

POR, OCP and UVP. The Power-On-Reset (POR) cir-

cuit can monitor the VCC, EN, and OCSET voltage to

make sure the supply voltage exceeds their

threshold voltage while the controller is running.

The Over-Current Protection (OCP) monitors the out-

put current by using the voltage drop across the upper

and lower MOSFET’s R_DS(ON). When the output cur-

rent reaches the trip point, the controller will run the

soft-start function until the fault events are removed.

The Under-Voltage Protection (UVP) monitors the volt-

age at FB pin (V_FB) for short-circuit protection, when

the V_FBis less 50% V_REF, the controller will shutdown

the IC directly.
